In the preferred form of construction, herein disclosed, each bary 5 is a channel bar withits channel disposed rearwardly. The front portions 9 ofthese bars, vwhich connect the side flanges 10 thereof, have their ends ico beveled at 1l, and these beveled ends as well c kresft'against the shoulder S andare welded v thereto'as indicatedV at 12, spot Welding bej' ingpreferably employed..
